Class SystemDatasetInstantiatorFactory

java.lang.Object

co.cask.cdap.data.dataset.SystemDatasetInstantiatorFactory

public class SystemDatasetInstantiatorFactory
extends Object

Creates SystemDatasetInstantiator instances for use in system contexts. This is used instead of directly creating a SystemDatasetInstantiator to ensure that the same temporary base directory is used, and so that the factory can be injected directly instead of injecting a LocationFactory, DatasetFramework, and CConfiguration object everywhere it is used.
